To all whom t may concern.'

Be it known that I, GEORGE B. DEACON, a subject of the King of GreatBritain, and a resident of the city of London, in the county ofMiddlesex, in the Province of Ontario, Canada, have invented certain newand useful Improvements on Garp'et-Sweepers, of which the following is aspecification.

This invention relates to improvements in carpet sweepers.

An object of the invention is to provide a sweeper in which the brushthereof may be readily and accurately adjusted vertically and retainedin the desired proximity to the floor.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel combination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in theappended claims.

In the drawings forming a part of this application and in which likenumeralsy of reference designate corresponding parts throughout theseveral views: Figure 1. is a plan view of the improved sweeper with thehandle thereof removed, and the bail partly broken away. Fig. 2 is acentral ver tical longitudinal section thereof. Fig. 3 is an endelevation of the sweeper. Fig. 4 is an end elevation thereof with theouter guard removed. Fig. 5 is a vertical transverse sectional viewshowing one inner end of the sweeper, and Fig. 6 is a detail horizontalsectional view through an end of the brush showing the trunnionarrangement therefor.

Referring more in detail to the drawings, the casing 10 is illustratedas being mounted upon four traction wheels 11 in the usual manner, whilethe central longitudinally positioned brush 12 is rotated through thefrictional contact. of said traction wheels upon intervening pulleys 13at the opposite ends of said brush. y

Two dust receptacles 141 of identical construction are hinged beneaththe opposite longitudinal edges of the casing and the description of onethereof will suffice for both.

The dust receptacles are hinged between the opposite end walls of thecasing, the hinging arrangement at the opposite ends of each receptaclebeing of different'construction. The two receptacles areoppositelyarranged so that the opening device for each is positioned atopposite `ends and sides of the casing.

'Inside of theY casing and upon one end thereof at a point adjacent theouter side wall 15, there is pivoted the flat .link 16 at the point 17while the opposite end of said link is hinged as at 18 to one of the endwalls of.- the receptacle 14e. The said link A16 is provided with anopening .19 therethrough for accommodating the axle 20 of the tractionwheel 11, which axle in turn passes through an enlarged perforation 21in each end 22 of the casing. The opposite end of the receptacle isprovided with the slot 23 foryreceiving the pin 24V upon the inner sideof the opposite end wall of the casing whereby said opposite end of thereceptacle is `pivotallymounted. For giving resiliency to the receptaclemounting, a spring 25 has its upper free end threaded through an eyelet26 upon the inner face of the end wall of said casing while the oppositeend of the spring is pivoted to the pin 26 upon the receptacle. Foropening and closing the receptacle upon said hinges positioned at itsopposite ends, there is provided the projecting end pin 27 which isconnected by a link 28 and the pin 29 to the operating lever 30 whichlatter in turn is Vpivoted to the outside of thecasing end at a point31. The operation of this construction vis clearly shown in Fig. l1 ofthe drawings.

An outer bracket 32 incloses 'the wheels and mechanism at each casingend. The top of each guard is firmly positioned parallel `to the casingend by means of the posts A33.

A material element of the invention about to be described consists o-fthe peculiarly-bent spring 34 which has its central portion formed in aloop 35 retained upon the ltop at the end ofthe casing by the screw 36.In opposite directions from said loop, the

`spring extends along the casing end `slightly projecting therefrom andafter encircling the opposite posts 33 is bent downwardly with itsopposite free ends 87 contacting the tops of the extended vtractionwheel axles 20, the cotter pins thereof being positioned outwardly ofsaid point of contact and thereby acting to retain the spring endsthereon. It will be noted that one lend of thetraction Wheel axle isprovided with the usual cotter `pin 38 while the opposite end thereofhas a spring member 39 secured to the casing end atthe point 40 andextending through said axle end. The position of said spring ends beingclear, it will be evident that the downward and 'inward tendency thereoftends to force the traction. Wheel axles in that direcloops 35 as willbe apparent from the drawings.

LThe mechanism designed for the vertical adjustment of the sweeper brushwill now be described.

A brush axle plate 42 provided with the boss 43 adapted for receptionwithin the annular socket 44 of the brush end is slidablymountedadjacent the inner face of the end guard 32 while being placed beneathopposite struck down lips 45. For the purpose of allowing said axleplate 42 to have vertical adjustment, the same is secured by the rivet46 to an outer slide plate 47 within the vertical groove 48 of the endguard. It is evident that a vertical movement of said plate 47 willcarry the end of the brush vertically, it being noted that for theaccommodation of the rivet 46, the end guard is provided with a shortvertical slot 49. For holding said brush end and its plate in thedesred'adjusted position, a channel piece 50 is positioned interiorly ofthe guard 32 and connected to the slide plate 47 by means of anadjustable set screw 51, the latter being accommodated in its verticalmovement by the slot 52 of the guard, through which slot the set screwextends. It will therefore be evident that upon loosening the set screw51, the end plate may be vertically moved, thereby adjusting the heightof the axle boss and the brush.

Vhile the forms of the invention herein shown and described are what arebelieved to be preferable embodiments thereof, it is nevertheless to beunderstood that minor changes may be made in the matter of form,proportion and minor details of construction without departing from thespirit and scope of the invention as set forth in the Copies of thispatent may be obtained for socket, said axle plate positioned interiorlyof said guard, a slide plate secured to said axle plate and positionedexteriorly of said guard within a slotted vertical depression of theguard, both said axle plate and slide plate being vertically movable, achannel member positioned within said guard, and an adjustable set screwpassing through the slot of said depression and extending through saidslide plate and threaded into said channel member.

2. A device of the class described comprising a sweeper casing, a guardsurrounding one end of said casing, a brush spindle provided with asocket in the end thereof, an axle plate, an inwardly-extending bossupon said axle plate and positioned within said socket, said axle platepositioned interiorly of said guard, and a slide plate secured to saidaxle plate and positioned exteriorly of said guard within a verticaldepression of the guard, both said axle plate and slide plate beingvertically movable.

3. A device of the class described comprising a sweeper casing, a guardon the end of said casing, a brush spindle provided with a socket in theend thereof, an axle plate, an inwardly-extending boss upon said plateand positioned within said socket, said plate positioned interiorly ofsaid guard,

said. guard being provided with a vertical depressionin the outer facethereof and having a vertical slot in the bottom of said olepression, aslide plate positioned in said depression, and a pin positioned throughsaid slot and connecting said axle plate and slide plate.

4. A device of the class described comprising a sweeper casing, a guardthereon, a brush spindle provided with a socket in the end thereof, anaxle plate, an inwardly-extending boss upon said plate and positionedwithin said socket, said plate positioned interiorly of said'guard, saidguard being provided with a vertical depression in the outer facethereof and having two vertical slots in the bottom of said depression,a slide plate positioned in said depression, a pin positioned throughone of said slots and connecting. said axle plate and slide plate, achannel member positioned within said guard, and an adjustable set screwpassing through the other of said slots and extending through said slideplate and threaded into said channel member.

In testimony whereof, I have signed in the presence of the twoundersigned witnesses.
